I expected & were packaged well. My overall
purchasing experience was very
positive."

- Thank you,
Marlene

"I recently found EcoDirect & have been
extremely happy with their service. They
have had all the PV modules, inverters,
optimizers and accessories I needed. They
provide excellent customer service & turn
orders around very quickly. I have switched
to EcoDirect for all my parts & materials
orders. Highly recommended."

- Zeno

"I wanted to let you know I am very pleased
with the service you gave & the quality &
condition of the solar panels I received
from EcoDirect. I will purchase more items
in the future from EcoDirect and will be
sure to tell others about your fine
operation."

Thanks,
Maurice

"Thanks EcoDirect! My solar system is up
and running; waiting for City and San Diego
Gas & Electric inspections this week; so
far so good!"

"I enjoyed ordering what I needed. It was
simple and fast, no issues what so ever. If
I need something else and its at a good
price, I will defiantly order from here
again. Also the shipping is at a good
price."

- Simon

My shipment arrived on time, as predicted.
Very, very good performance by EcoDirect.
What more could you ask for from an online
material supplier? Looks like the quantity
from Quick Mount is spot on & the rails
were bundled safely. EcoDirect will be my
recommended source to my friends &
neighbors for solar.- Thank you, Jim

Description

KidWind Airfoil Balsa Blade Wood Sheets

This balsa is pre-shaped in an airfoil shape. Real wind turbine blades use this airfoil shape to generate lift and reduce drag, making for highly efficient rotors.

Experiment with advanced blade designs and explore Bernoulli’s Principle with these airfoil sheets. Well-designed airfoil blades will be noticeably more efficient than similarly shaped flat blades.

Sheets are 12 in. long, 3 in. wide, and 1/4 in. thick at the thickest section of the airfoil profile.

Length

12 in.

Width

3 in.

Thickness

0.25 in

You Can:

Cut and shape your own wind turbine blades

Experiment with number of blades

Experiment with size and shape of blades

Experiment with angle of blades

Concepts

Understanding differences between energy and power

Exploring concepts of lift, drag, and torque

Understanding angles

Developing and using physical models

Understanding the relationship between forces and motion

Understanding the relationship between energy and forces

Understanding clean energy

Exploring energy transformations

Analyzing and interpreting data

Optimizing designs

Designing controlled experiments

Frequently Asked Questions

How do I attach my blades to the dowels?

We recommend hot glue (glue gun). Other types of glue or duct tape may also work.

How many sheets will I need for my classroom?

Good question! This is one component of wind turbine experiments that is considered "consumable." We recommend starting students with simple, cheap materials like cardboard, paper plates, and cardstock. Then allow them to make advanced designs using the corrugated plastic. You can also group students into "teams" to save material. Most teachers use 50-100 sheets for a class of 30 students.

What is the best way to cut balsa wood?

The balsa tends to split and break if you use scissors. Hobby knives work well; just be VERY careful. We recommend adult supervision.
